Test R6:






Normal Operation
The restraints control module (RCM) monitors the driver seat track position sensor circuits. If the RCM detects a short to ground, it will store diagnostic trouble code (DTC) C1947 in memory and flash lamp fault code (LFC) 49 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A driver seat track position sensor short to ground fault can be caused by:
- damaged wiring, terminals, or connectors.
- a faulty driver seat track position sensor.
- RCM is faulted.
